concurrency
===========

This module provides concurrency primitives useful for multi-threaded
programming such as:

* :hpx:class:`hpx::barrier`
* :hpx:class:`hpx::util::cache_line_data` and
  :hpx:class:`hpx::util::cache_aligned_data`: wrappers for aligning and padding
  data to cache lines.
* various lockfree queue data structures

See the :ref:`API reference <modules_concurrency_api>` of the module for more
details.
